Thanks for the reply.

We will probably hold off on playing hockey for a while. But unsure about other activities.

For example, playing musical instruments. If I knew the headaches were something that he simply has to deal with going forward, we would treat the headaches as we can but try to resume most normal activities. So I would encourage him to play his instruments, even to try to play a bit past once the headaches start, to try to work through them. If the pain is so much that it is not bearable, stop, but if the pain is little more than a nuisance, play through it, and maybe by doing this would be able to deal with better over time.

On the other hand, if I knew that abstaining entirely from musical instruments (or video games, or TV, or whatever) for a period of x days would make the headaches go away for good, we would obviously do that! But hate to restrict all activity in hopes of it curing the headaches if the reality is the headaches will come and go regardless of whether activities are done or not.

For a case like this, is there any evidence that would support restricting activity for some period of time (a week? a month?) would improve our chances of the headaches going away for good (or for a long period of time)? Or any evidence to the contrary - that resuming normal activity would help one deal with the headaches better than restricting activity?
